我厂每天加工下来的大量切屑,过去都把它当废物,任其风吹雨打,一直没有加以利用。最近几期“铸工”连续刊载有关熔化切屑的技术资料,在上级的领导与支持下,冶金科和车间的技术人员进行了学习,深入了解切屑在冲天炉中的全部熔化过程及燃烧原理。为了检查理论与实际情况结合的正确性,以及决定工艺上的一些参变数,曾进行多次试验和生产性的熔化。 I plant a lot of processing down the day of the chip, in the past it was a waste, let its wind and rain, has not been used. In recent years, “Castor” continuously published technical information on melting chips. Under the leadership and support of superiors, metallurgical and workshop technicians conducted a study to understand thoroughly the melting process and combustion principle of chips in a cupola. In order to check the correctness of the combination of theory and practice, and to determine some parameters of the process, several tests and productive melts were conducted.
